Dragon Dad is an episode of the ALVINNN!!! and The Chipmunks series.
Theodore beats Alvin at a video game when the door bell rings and Theodore excitedly answers it only to be disappointed to find a salesman. Soon after Alvin's invited to Sandy's party, his brothers attempt to get Theodore to explain the reason he's answering the door so fast, but he refuses to tell. They spy on Theodore as he collects sticks and feathers for a nest when Jeanette calls down to him. Upset that Theodore confided in them and not him, Alvin confronts The Chipettes only for Brittany to counter citing Alvin's inability to keep a secret. Theodore finally reveals that he bought a dragon egg through a secret society, much to Alvin's dismay. Alvin and Simon argue to Theodore that he's been conned and he lost all his money for nothing, but when Dave finds out he makes them respect Theodore's mission. The elder siblings are tasked with egg duties while Theo protects the egg from the evil troll king. Once the instructions are finished, the egg is ready to be hatched under the full moon. Desperate to go to a party and being unconvinced the egg will even hatch, Alvin talks Brittany into pretending to be the evil troll king in order to steal the egg without affecting Theo's beliefs. His brothers learn Brittany stole a decoy egg and, when they go to find the real egg, Brittany is discovered to be the evil troll king as well. The real egg is found broken and a shadow of the dragon envelops them from above leaving Alvin, Simon, and Brittany to run away in fear while Theo walks away happily.
